FEED-MILL.

' Specification of Letters Patent.

latented Jan. 12, 1909.

Application filed June 28, 1907. Serial No. 381,235.

To all whom it may concern:

Be it known that I, Roscoe S. TOMKIN- SON, a citizen of the United States, residing at Rush, in the county of Monroe and State of New York, have invented new and useful Improvements in Feed-Mills, of which the following is a specification.

This invention relates to a regulator for feed mills.

The object of the invention is to provide a simple and thoroughly eflicient governor for use in connection with the feed governors of attrition mills or any other machine where the amount of feed going through the machine is to be positively controlled, whereby the capacity of the machine will be measurably increased as it results in positively regulating the feed according to the power.

The present invention is especially adapted for feed mills driven by water power as it operates in a positive manner to hold the motion uniform, irrespective of the quantity of grain or straw that may be in the feed, and will also permit of one or more machines being operated or thrown into or out of operation without the necessity of changing the quantity of water supply to the wheel.

While particularly adapted for use in connection with water wheel-driven machinery, it is to be understood that it is applicable to machinery driven by other motive power, such as electricity or steam, and as this will be readily understood, detailed illustration thereof is omitted.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a governor for feed mills, as will be hereinafter fully described and claimed.

In the accompanying drawings forming a part of this specification, and in which like characters of reference indicate corresponding parts-Figure 1 is a view in side elevation, partly in section, of a governor constructed in accordance with the present invention, and, Fig. 2 is a detail view of a portion thereof.

Referring to the drawings, 1 designates the hopper into which the grain or other material is fed, and beneath which is arranged a shoe 2, as usual. Arranged at one side of the hopper is a casing 3 in which is disposed the governor shaft 4 that is supported for rotary movements in a bearing 5 carried by the upper edge of the casing and a step-loar6 arranged on the upper edge of the hopper. The upper end of the shaft carries a beveled gear 7 that is engaged by a similar gear 8 upon a countershaft 9 supported in suitable brackets 10 and carrying a pulley 11 that is engaged by a belt 12 driven from a suitable source of power, not necessary to be shown. The lower portion of the shaft 4, for a distance approximating about one-half, more or less, is hollow and is provided with alined, longitudinal slots 13 in which works a crosshead 14, and through this latter projects a bolt 15 having a head 16 bearing upon the cross-head. The lower end of the bolt is provided with an eye 17 which is engaged by a hook 18 formed on the up or end of a link of wire the lower end of w ich is provided with a similar hook 19 that engages the inner end of a lever 20 fulcrumed on a standard 21 supported by the bottom of the casing. The outer end of the lever 20 is engaged by a hook 22 carried by a length of wire, the other end of which is formed into a similar hook 23 that engages with an eye 24 in one member 25 of a rock-shaft 26 journaled in suitable bearings 27 carried by the ho per, the other member 28 of the rock-shaft liaving secured to its terminal a paddle 29 disposed over the shoe, as clearly shown in Fig. 1.

It will be seen by the arrangement of the governor that when the balls 30, which are connected by arms 31 with the shaft 4, as at 32, and with the cross-head by arms 33, start to assume a horizontal position, under rotation, an upward draft will be applied to the bolt 15, and this motion, through the medium of the hook members 18, 19, lever 20, hook members 22 and 23 and rock-shaft will tend to lift the paddle away from the shoe and thus permit the escape of material. As the speed of rotation of the governor increases the paddle will be lifted still further away from the shoe, thus to let more of the material escape, but as the speed decreases the paddle, or more properly the cut-oil will approach the shoe and thus check the escape of material. If at any time the motion is too high or excessive, means is provided whereby the governor may be permitted to rise and the cut-off to fall back and let more feed in and thus choke the motion down to the point desired. This regulating means comprises an eye bolt 34 that projects through a crosspiece 35, and carries at its upper end a thumb nut 36. Connected with the eye-bolt is one terminal of a coiled spring 37, the other terminal of which is attached to the lever .20.. By loosening the thumb nut, the tension of the spring Wlll of course be lessened, whereby the resistance to rotation of the governor will be diminished, and it will be more r e; sponsive in action. Ihe reverse of this. will of course Occur if the spring is placed under increased tension.

It will be seen from the foregoing description that the device herein described, While simple in character, will be found thoroughly efficient in use and will in a practical manner, control or regulate the discharge of material from a feed mill.

What I claim is 1. A regulator for feed mills comprising a rock-shaft, a cut off carried by one end thereof, a governor, a member having a. reciprocatory connection with the governor, a

member-and the lever and the lever and the rock-shaft, and means connected with said lever for exerting abraking action thereon. r 2. A regulator for feed mills comprising a ook-shaft, one member of which is provided with a terminally. curved paddle, ashoe with which the'paddle cooperates, a out-offcarried byone end of the rock-shaft, a governor, a member having a reciprocatory connection with the governor, a lever, connections'be: tween the reciprocatory member and the lever and'the lever and the rock-shaft, and

a braking action thereon.

In testimony whereof, I
